Zusammenfassung

Die Gasextraktion aus reduzierender Schmelze wurde zur Stickstoffbestimmung in Uranmetall- und Urandioxid-Referenzmaterialien bei Gehalten von 10–15 μg·g−1 angewendet. Bei Temperaturen über 2700° C ist kein Platinbad mehr erforderlich. Zur Eichung der Detektionseinheit im Bereich von 1,5–670 μg wurden reiner Stickstoff oder Stickstoff-Helium-Mischungen benutzt. Zur Eichung der Extraktion wurden metallische Referenzmaterialien mit (8–331μg) N2 eingesetzt.

Summary

The reducing fusion gas extraction method has been used for the determination of nitrogen in uranium metal and uranium dioxide reference materials at levels of about 10–15μg·g−1. It has been found that when extracting at temperatures above 2700° C the use of a platinum flux is no longer necessary. Pure nitrogen and nitrogen-helium mixtures were used for calibrating the detection unit in the range of 1.5–670 μg. The calibration of the extraction was performed with metallic reference materials in the range of 8–331 μg N2 content.
